If the setup instructions above don't work for your particular OS setup, for whatever reason, you can get the ball rolling by installing these tools in whatever way you can and then getting them to work with the Makefile in circuitpython/atmel-samd (2.x branch) or circuitpython/ports/atmel-samd. (master branch):
- git
- make
- python2
- python3
- gettext
- ARM gcc toolchain: https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads
